If WMA Playback failures occur after you've verified that the Windows Media Subsystem is correctly installed (as described at:http://www.mediamonkey.com/support/index.php?/Knowledgebase/Article/View/90) or if you receive an error: '...Some of the tracks are protected by Digital Rights Management...' or 'ModName: Indiv02.key or Indiv02_64.key' then it is probably due to to the fact that the tracks are protected by Digital Rights Management (DRM) and: o you do not have rights to play them, the rights may have expired o there is a problem with the DRM certificates on your system (e.g. if you copied DRMed WMA files to a new machine) or if the Windows DRM Cache has been corrupted by an application that modifies the cache.

Some solutions that have worked for some users include:

a) If you use the Netflix movie player (http://www.netflix.com), try to run: C:\Program Files\Netflix\Netflix Movie Viewer\ResetDRM.exe

b) Delete the whole DRM folder under C:\ProgramData\Microsoft\Windows\DRM\Cache as follows: 1. Kill all instances of Internet Explorer using Task Manager 2. Rename the DRM directory at C:\ProgramData\Microsoft\Windows\DRM 3. Run IE as administrator 4. Run DRM Upgrade at http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp

c) Revert the DRM Cache to an earlier uncorrupted version: 1. Navigate with Windows Explorer to C:\ProgramData\Microsoft\Windows\DRM\ 2. Right clicked the Cache folder -> Properties -> previous versions 3. Revert to a previous version of the folder before the error started to happen.

If this fails, contact the store from which you originally purchased the DRMed content.
